Do I have lupus? Posisitve ana with a titer of 1:40 homogenous plus a elevated crp level 1.2 also protein in the urine.

Lupus. Unlikely, but you need a proper workup including quantification of proteinuria and presence of other lupus symptom. Your ANA level is slightly high which is nonspecific. You should see a nephrologist if you are concerned about LUPUS. .
